Really? My Roma really rocks with 9886/41001. From my experience roma sucks balls when used with restrictor anything smaller than a 7mm. I broke mine in with 9mm for a gallon and another gallon with an 8mm and now im on my 3rd gallon using 7mm. It rocks my world and i still have metal pinch and gets stuck up top. Used it with buku cap since new. Runs around 250-280 with 30% byron 9% oil.
